UTF-8 is a format that encodes each character in a string To understand this, it’s helpful to understand what UTF-8 is in theįirst place. If you try it with 127 or less, it round trips just fine. WTF?! The data was changed and the original value is lost!
Simulates that scenario with a byte array containing a single byte, 128. Later on, you need to relay that data so you take it out, encode it back Imagine you’re receiving a stream ofīytes and you store it as a UTF-8 string and pop it in the database. WhatĪre the cases in which you might lose data? Round Tripping UTF-8 Encoded Strings
I’ve always known that if you need to sendīinary data in text format, base64 encoding is the safe way to do so.īut I didn’t really understand why the other encodings were unsafe. When you need to represent binaryĭata in a string, you should use base64, hex or something similar. In response to an earlierīasically, treating arbitrary binary data as if it were encoded text That this wasn’t the first time Skeet answered a question about usingĮncodings to convert binary data to text. Not to give you the impression that I’m stalking Skeet, but I did notice To encode the binary data as text, then decode Which genuinely is encoded text - this isn’t.
Encoding is for when you’ve got binary data You should absolutely not use an Encoding to convert arbitraryīinary data to text. In fact, I have a story about this I want to tell you in a future That isn’t exactly their code, but this is a pattern I’ve seen in the
